Iāve been following this thread for a looooong time. On a whim, I decided to try some of the Dolby Vision files that were previously stuttering / having sync issues. With my AppleTV set to match content, the plex advanced settings to āuse old player: offā and āuse old audio engine: onā, the files played back as a direct play without stuttering or sync issues for both Dolby Vision, HDR10+ and regular 1080p SDR content.
I havenāt tried restarting plex or my AppleTV yet, but wondering if anyone else has had luck recently. Using the latest AppleTV app and 1.40.0.7775 on the server.
Infuse can do DDP Atmos, which is what all the streaming apps use. It canāt do TrueHD Atmos, which is what you find on blurays.
I have kept this thread open to read mostly while Iām on the toilet but I think the time has come to stop following. Plex on ATV is a bad experience plain and simple. They donāt even have good playback controls, let alone support for advanced formats. I am using PlexHTPC with a different mpv version with some configuration and it works great. I get support for everything A/V I want now. It just sucks I have to change to my computer. Itās already on the same TV but it would be amazing to keep everything media related in ATV.
Non-4K/HDR I still use ATV for Plex or Channels.
Funny to see the ChannelsDVR guy in here. I love Channels and I have a yearly sub, but they have their own set of issues. I applaud them for not targeting as many clients as Plex, but they still have a long way to go before being a serious competitor. Their personal media support leaves a lot to be desired. The OTA is pretty solid but quirky. Still too many sharp edges compared to a sling or whatever.
Give me the personal media features of Plex + the LiveTV/DVR features of Channels and Iād have a perfect app. I think a lot of people are stuck using both at the moment.
EDIT: I donāt have a plex pass but it shows it near my name. I only had one for a couple months and realized I didnāt need it and I donāt like lifetime subscriptions. If you have plex pass and experience the issues like ATV has I surely hope you donāt renew. They can then either fix the issues or start to do stuff like put HDR behind plex pass. Thatās when I go old school HTPC.
Oh man, this issue is really driving me mad. 4K HDR high bitrate videos work fine on my LG TV, Android TV, Fire TV stick, even my iPad butā¦ the Apple TV app stutters, drops frames and loses audio sync. Is there a beta testing option for those really keen on a solution?

There is a beta. Howeverā¦
Itās constantly full.
Thereās absolutely nothing going on whatsoever in the beta to address the numerous issues.
Meanwhile Plex are (last time I checked) still trying to hire a playback engineer for Apple devices. Thatās been ongoing since the last quarter of last year.
So Iāve been fighting this issue for more than a year it seems like. It seems to not be as much of an issue with MP4 files, but MKVs are a train wreck. I have Apple TV on all our TVs and it drives me insane to see the audio get gradually more and more out of sync until I have to stop playback and start again so I can have a few minutes of tolerable lag.
Iāve tried the new audio offset feature in the new player release, but the problem is the sync is not consistently off. there are times it seems to be only 5-10ms off and then 1,000-2,000ms, then 200ms then back to 10ms.
PLEASE will someone from the Plex team let us know what the status is on this. even if it is āwe arenāt going to fix itā or āits in the backlog, but lowest priorityā or whatever. just having radio silence is painful.

I do also have audio sync issues.
For the last 2 films I watched, I had to add 100ms delay on my AVR to get something watchable.
Offering a rental service is nice, but please fix the basics first.
- I do have match color space / framerate enabled
- I run an Apple TV 4k gen3
- Problem is specific to Plex, it works fine with other streaming services (Disney, Netflix, ā¦). It also seems to be specific to some video & audio stream combinaison - because for some content it works fine

The only way i know of to not have all these issues and still utilize my plex server is to use infuse coupled to my plex server in direct mode. As long as plex doesnāt fix this then infuse is really the only way.

Infuse is the way!
However, if youāre using Airpods adjust audio delay to +150ms. Then itās perfectly synced.
Tv speakers do not need any adjustment.

Use the audio calibration in the ATV settings, that should sync up the AirPods.
Sadly, it doesnāt have an effectā¦
Seems like theyāre working on migrating to Metal.

In other news for those of us still waiting for our invitesā¦ Infuseās latest update last week added the ability to access our Plex Watchlist which is pretty huge. I didnāt think there was even an API for that but props to them for however theyāve done it, it was one of my biggest downsides to using Infuse.

Whatās the latest guys? This stuttering/audio sync issue has been a nightmare for me and Iām sure for many of us. What does Plex need from me to get this problem solved?
